The Leo Triplet

Unread post by Pete »

31 March 2024

The dome shutter was inoperable all winter, but we caught a warm dry day mid-March and it was finally repaired with my sons doing the heavy lifting.

Sunday night started out with a little haze, and while I’ve done better on the Triplet using the Hyperstar I can't complain as the sky turned quite murky toward the end of this run.

Leo Triplet – galaxies M65, M66 and NGC 3628
31 Mar 2024 20:22 – 23:16 hrs. EDT
59 X 3 min, unbinned, -15°C cooling, 200 gain, 2 Hz guide rate
Explore Scientific 102mm refractor with LP filter and ASI2600MC-P camera

Conclusions & lessons learned:
It was a relatively warm night (60° F) and I was pleased to be able to cool to -15C as that was the highest temperature for the various darks I’d run in the winter.

Happy to be back in the imaging saddle once again.

Nice shot of Leo Triplet...which is one of my favorite galaxy groups.

Good to see you are back imaging. Now if we can only get a few good clear nights...
